Using the dynamic Phase Inversion Temperature (PIT) as a fast and effective method to track optimum formulation for Enhanced Oil Recovery

Abstract

Considering the PIT shifts and shapes, it is possible to infer relevant information on the crude oil such as precise EACN and relationships between optimum salinity and temperature. The "PIT-Slope method" allows ranking EOR surfactants according to their amphiphilicity. Mixing both results allows a faster determination of key parameters used in EOR compared to studies with equilibrated system.
